On some cases (noticed from log) that there is a crash in
libhwui.so, future debug log shows that the light center position
values are nan, causing an out of bound access in hull function
in SpotShadow.cpp for parameter retPoly which assume to be of
maximum length of pointsLength only but not the case when all
points are nan.
More log shows that a Snapshot was created (new) without
mRelativeLightCenter begin set, and Layer.cpp trying to
use it by calling updateLightPosFromRenderer. Those values
are random values in stack which causing math calc based on
that value returning nan also.
Initialize mRelativeLightCenter to 0 in Snapshot.cpp to avoid the
problem.

By using computeFrameTime AnimationContext would
potentially end up modifying the latest vsync if
a very-slow frame was received from the UI thread.
This could potentially desync animations that were
RT & UI thread 'synchronized', but more significantly
it would confuse the swap chain which tries to only
draw one frame per vsync causing unneccessary frame
drops.

Align x offset and width to 32, y offset and height to 4.
It improves the font texture upload performance.

Primarily fixes case where 0 dimensioned layers could be
created/updated. Additionally, adds more logging in incomplete
framebuffer cases, if they still occur.

HWUI: do not call glCopyTexSubImage2D on empty area.

Previous check .isEmpty() is not sufficient, because getWidth() may have
value 0.5, so technically it is not empty, but when this size is passed
to texture calls it is converted to uint_32 and it becomes zero.

the VD tree structure, but also the properties of the VD tree,
such as alpha.

saveLayer clips the layer to the size it needs to
be and will translate content if necessary, but
the drawLayerOp that results from that was not
translated to handle the shifted draw content.
